Any DCS World keys purchased from other sources are invalid and are simply trying to re-sell keys that are bound to other users or purchased through fraud. Such sites include Kinguin, CDExpress and G2A.

If you purchase DCS World keys from these sites, we cannot help you. We suggest you contact these sites for a refund.

I've just tried the mission after restarting DCS (after a permanent freeze on the loading screen, pretty much the only thing DCS is achieving consistently lately...) and I can't get the communication menu to show up.

Here is the requested screenshot of the directory. Left side the directory where autoexe.cfg is installed and right side the path to the JSGME _mod directory. For this time only racegate is installed in DCS 2

Oh no, I'm sorry, I meant could you attach the autoexec.cfg to your post, the file itself.
I'm just trying to narrow down the origin of the issue, I'm quite clueless right now
But no worries, we'll get it working

Thanks for this mission. I have a slight issue with it so far. I've only loaded i up to see if it loads OK, haven't flown anywhere yet, but I have no waypoints marked on the kneeboard map. Just a waypoint which says something like "new static object".
